Start the Week - Learning from apes, fish and wasps

Adam Rutherford explores how other species can help us understand our own. The world-renowned primatologist Frans de Waal has spent decades observing the behaviours of chimps and bonobos. In Different: What Apes Can Teach Us About Gender he looks at, and questions, the interplay of biology and culture. Using his knowledge of apes he challenges widely held beliefs about masculinity and femininity and assumptions about authority, power, cooperation and sexual behaviour.

Nichola Raihani’s research focuses on the evolution of social behaviour in humans and non-human species. In her book, The Social Instinct, she looks at the science of cooperation and how humans have evolved socially and built, and fought over, hugely complex communities. But she also suggests we might have something to learn from the pied babblers of the Kalahari, and the cleaner fish of the Great Barrier Reef – two of the most fascinating and extraordinarily successful species on the planet.

While ants and honey bees are often held up as exemplars of social cohesion, the entomologist Seirian Sumner wants to rehabilitate the much-maligned thug of the insect world, the wasp. In Endless Forms: The Secret World of Wasps she shows how wasps are older, cleverer and more diverse than their evolutionary new-comer the bee. And she makes the case that they hold hidden treasures of relevance to human culture, survival and health, and one species even taught us how to make paper.

More or Less: Behind the Stats - Are just 100 companies responsible for 71% of global emissions and how stressed are South Africans?

In the fight against global warming we?re constantly told to do our bit to reduce green house gas emissions. However, a claim circulating that just ?100 companies are responsible for 71% of global emissions? can make any individual effort seem futile. But does this claim mean what you think it means? We look into this and the claim that the pandemic pushed South African stress levels up by 56%. With guests Abbas Panjwani from Fullfact and Kirsten Cosser from Africa Check.

Start the Week - The body clock and sleep

Every moment of the day tiny biological clocks are ticking throughout the body, but Russell Foster, world-renowned expert in circadian neuroscience, warns that modern life is playing havoc with these ancient and delicate mechanisms. In his latest book, Life Time: The New Science Of The Body Clock And How It Can Revolutionise Your Sleep and Health, Professor Foster reveals how this essential part of our biology works. He tells Tom Sutcliffe how new understandings about our daily routines could help reset how we live and sleep.

ViSiBLE is a professional theatre company dedicated to creating new and provocative works, with and about older people. Its latest performance, Five Characters in Search of a Good Night's Sleep, is at the Southwark Playhouse until 21st May. ViSiBLE’s founder, the playwright Sonja Linden, says the new piece was inspired by the experiences of the actors who as they’ve aged have found sleep more elusive and sleep-inducing techniques more desperate.

Ros Holmes is a lecturer in Chinese Studies at the University of St Andrews. Her research focuses on ideas about sleep and insomnia, and how they’ve been represented in the visual culture of twentieth century and contemporary China. From the images of ‘national awakening’ in the early years of the Republic and the always-alert workers of the Cultural Revolution to the cities that never sleep today – sleep deprivation has become part of life in China.

More or Less: Behind the Stats - Did the WHO get some of its excess death estimates wrong?

The World Health Organisation recently released some new estimates of the global death toll of the pandemic. But the figures for a few countries have caused controversy. Tim Harford speaks to Professor Jon Wakefield, who worked on the analysis - and Indian data journalist Rukmini S about the debate that?s erupted in India over the figures.

Start the Week - Marwa Al-Sabouni – Rebuilding with hope

The Syrian architect Marwa al-Sabouni is the Guest Co-Director of this year’s Brighton Festival and her flagship project The Riwaq on Hove seafront provides a space for social and artistic exchange. Rebuilding is the festival’s theme and the subject of her latest book, Building for Hope – Towards an Architecture of Belonging which explores how cities can be rebuilt after crisis and war. She tells Helen Lewis that architecture has a pivotal role in generating community, not just in devastated cities, but all around the world.

Dame Jo da Silva is an engineer at the building firm Arup who specialises in disaster relief. After years spent realising the high designs of architects for everything from airports to bus shelters, she became involved in projects to rebuild communities hit by catastrophes. As urbanisation reaches record levels globally she argues that it’s more important than ever to build in sustainability and resilience.

The historian Jessie Childs focuses her story of the violence and disaster of the English civil war on The Siege of Loyalty House in the 1640s. To the parliamentarians Basing House, the royalist stronghold, was the devil’s seat. Over two years, the inhabitants were bombarded, starved and gassed from the outside, and faced smallpox, spies and mutiny from within.

More or Less: Behind the Stats - Have the oceans become 30% more acidic?

Although the climate-changing effects of Carbon Dioxide emissions are well known, they are changing our oceans too, making them more acidic. But how much?

Tim Harford explores the statistical quirks of ocean acidification, from pH to the mysteries of logarithmic scales. With Dr Helen Findlay from the Plymouth Marine Laboratory in the UK.

Start the Week - Curiosity, ingenuity and experimentation

Wonder at the natural world has inspired people and fuelled curiosity for millennia. The ancient Greek Theophrastus had interests that spread far and wide, from biology and physics to ethics and metaphysics. But although he was Aristotle’s friend and collaborator, and his notes on botany inspired Linnaeus, his name has mostly been forgotten. The writer Laura Beatty’s new book, Looking for Theophrastus, aims to rescue him from obscurity.

The scientist, Suzie Sheehy, still feels a childlike wonder at the way physics seems to be able to describe everything – from the smallest subatomic particle to the scale of the Universe. In The Matter of Everything: Twelve Experiments That Changed Our World, she looks back at the people who engineered ground-breaking experiments, and the human ingenuity, creativity and curiosity, as well as luck and serendipity that propelled them forward.

While physicists attempt to describe and define the universe, the workings of the human mind still remain a challenge to scientists and philosophers. In The Book of Minds, the science writer Philip Ball looks at what we know about the minds of other creatures, from octopuses to chimpanzees, and of the workings of computers and alien intelligences. By understanding how minds differ, he argues, the better we can understand our own.

More or Less: Behind the Stats - Sweden?s polarising pandemic response

When much of Europe went into lockdown at the start of pandemic, Sweden?s lighter touch strategy got lots of attention. Fans of the approach say it was a huge success that showed lockdowns were pointless. Opponents say it has been a disaster. But what do the numbers say?

In this episode of More Or Less, Tim Harford and journalist Keith Moore carve a nuanced path through one of the pandemic?s most polarising approaches.

Start the Week - The age of the strongman leader

In The Age of the Strongman, the journalist Gideon Rachman explores how populist and authoritarian leaders have become a central feature of global politics. Since Vladimir Putin took power in Russia at the beginning of the new millennium, self-styled strongmen have emerged across the globe, from Trump and Bolsonaro to Orbán, Xi and Modi. Rachman tells Tom Sutcliffe how these leaders have taken power and the challenge they pose to liberal democracy.

Judy Dempsey is a senior fellow at Carnegie Europe and editor in chief of the Strategic Europe blog. She explains how Viktor Orbán has tightened his grip on power in Hungary, while the EU has dragged its heels. And how Putin’s war in Ukraine has not only exacerbated pre-existing global divisions but divided Europe as well.

History is littered with powerful leaders, and Christopher de Bellaigue, tells of the rise of one of the most feared – Suleyman the Magnificent. In The Lion House: The Coming of a King the 16th century Ottoman Sultan dominates the lives of those from Baghdad to the walls of Vienna.

More or Less: Behind the Stats - Understanding India through Data

How do you go about understanding a country with a population as diverse as it is vast?

Data journalist Rukmini S is the author of Whole Numbers and Half Truths: What Data Can and Cannot Tell Us About Modern India. Tim Harford spoke to her about the power and pitfalls of using statistics to make sense of modern India, from basic questions like average income to the huge challenges of keeping track of Covid.
